, Loon-FA s TENme. For:

' Be it known that LJA OBDJSoHAEFFER, a

icitizen of the United States, residing at Mun-Q cie, ;-in. the countyof, Delaware and State of rIndiana,haveinvented certain new and useful Improvements in 'Floor-Fastenings for Fu rniture, of which the following is'a specification. I h This invention relates to a meansfor rea, movably securing school-desks tothe floor;

and the object of the invention is to provide a fastener which will unlock the desks, and

therebytpermitthem to be tilted forward into an inclining. position, and thereby leave the f floor"underneaththefdesk unobstructed, so

that the samelmay be thoroughly cleaned. The invention consists, further, ina fastener w'hereloythe school-desks may be entirely'rekeep the floor in a sanitarycondition.

Thereare other features, and] the construction and arrangement of the several parts. of

such a fastener whereby. the ad vantages sought are attained will be more particularly described in the annexed specificationand the novel featuresthereof then pointed'out in the claims.

Referring to the accompanying drawings,

which are made a part hereof, and on which similar numerals of reference indicate similar parts, Figure l is a side elevation of aschooldesk, showing my fastening device in operat ing position. Fig. 2 isa fragmentary detail perspective view of the'lower. end of a forward leg of a school-desk, showing the construction of the fastener employed on said legs of the desk. Fig. 3 is a fragmentary detail perspective view of the fastener employed on the rear legs of thedesk. Y

In the drawings, 1 is the frame of an ordinary school-desk; 2, the top; 3, a receptacle for retaining the school-books, and t is a seat which is'pivotally securedto the frame 1 and which may be moved into a vertical position. (Shown by dotted lines in Fig. 1.) This construction of the seat isold, and while the elevation of the seat permits the floorunderneath to be more easily cleaned no provision has desk where the latter attach to the floor.

I Patente'd I jec. 5, "1905 i 7 besecured. The rear legs of the'desk areprovided witha hinge 6, which iscomposed oftwo members pivotally connected together, i

one of said members being secured to the floor, whilethe other isprovided with an aperture which registers with thedowel-pin 8, mounted on the rear leg ofthe desk. I

As the school-rooms are-swept daily, it will be seen that a'fastener that permits the desk to'be thrown forward,leaving thefloor und'ervneath unobstructed, will greatly facilitate the 'workin cleaning the room. When a general cleaningandj 'scrubbing is desired, at which time it is desirable to remove the entire desk from its position on the floor, I provide a fastener, which issecured to the forward legsof 1 i This the desk, which permits such removal.

fastener comprises'two members 10 and 11,

hinged together. The member 10 is rigidly secured to th'eforward legs of the'desk, while the member 11 rests upon the floor andis provided at the forward end with the right-angle shoulder12. The membe'rll passes through fast'rap 15, which is rigidly secured to the floor. Thestrap 15 is notched to permit the member 11 to pass and is also providedwith the secondary notch 16 which forms a passage-way for the shoulder 12 on the forward end of the member 11. The strap 15 is also provided with a locking-plate 20,which is pivotally mounted in said strap 15,the plate being cut of a length that when the member 11 of the fastener has been movedthrough the strap 15 tonormal positionthe locking-plate 20 can be lowered to engage the rear surface of the shoulder 12. This construction preventsthe member 11 from being removed from the strap 15 until the locking-plate 20 has been disconnected from the shoulder 12, as shown by the dotted position in Fig. 10f the drawings. While the forward portion of the desk is held against lateral or longitudinal movement on the floor the desk may be swung forward,-when the fastener '6- is released by means of thevpivotal connection 'of the members 10 andll ofthe forward fas-I tener. Thus it will and economical manner provided afastener for school -desks which permits their ready rebe seen that I have in a simple,

movaLsothat the school-room may be kept in f a more, cleanly and sanitarycondition than is now possible by the present means of rigidly securing the legs of the desk to the floor,which method always permits dust and dirt to accumulate land afford a ready place for the breeding and transmission of diseases.

Having thus fully described my said invention, What I claim as new, and desire to secure by Letters Patent of the United States, is'' 1. In a fastener for school-desks, the combination with the deskframe,h=inges comprising a plurality of members pivoted together, part of said members secured to the desk-legs and the free members contacting the floor, a shouldenformed on theends of the free members, a notched strap for engaging the free ends of the hinges, and a retaining-plate pivotally mounted in the notched strap that engages the shoul der on the free members of the hinges and operating to prevent the accidental separation of 20 the parts.

In Witness whereof I have hereunto set my hand and seal, at Indianapolis, Indiana, this 16th day of May, A. D. 1905.
